I could see you making a sale on this one. It's a good name for a website discussing classic TV.
It's short and easy to remember which is good.
I note there is a Gold TV station in the UK.
"TV Gold" is a common expression.
So, yes, the domain has some attractions. I don't see an easy sale and it's not ultra valuable. I would not have registered it myself because I don't see the chance of a sale as strong enough, but there is certainly a chance of a reasonable sale.
